In reply to Lewis Robinson:
What gear are you looking for in particular and what do you have already?
I see in your logbook you've logged exclusively grit; is that what you'll be starting out on? If so, you'll be able to get by with a single set of nuts, about 6 quickdraws, a single rope, couple of slings and preferably a few medium cams (0.5, 0.75, 1 & 2 in Camalots, or purple, green, red and yellow).
The nuts you can get second hand. You can pick up a set of silver Wild Country Rocks 1-10 for cheap (there is a set on FB Marketplace for £20). If you've climbed sport previously then you might already have the rope, slings and QDs. Short sport draws are mostly fine for grit and nylon slings are cheaper and wear better than pricey dyneema. You can make a saving with your cams by getting them in a set (Black Diamond and Wild Country both do multi-packs which work out <£50 per unit. DMM Dragons seem to be a bit more expensive).
I wouldn't recommend getting anything soft (slings, cams, rope, quickdraw dogbones) secondhand but nuts and krabs should be fine if they pass visual inspection.
If you can't afford cams yet, you could get secondhand hexes cheap and have a proper trad apprenticeship but you will want to cut the softs off them and re-sling with appropriate cord (will cost about £2 per hex in cord).
